Documents & packaging
What Documents Should Buyers Ask Chinese Suppliers For?
A practical guide for overseas buyers deciding which supplier documents, certificates, product files, and testing information to request before samples, RFQs, or orders.

Short answer
Buyers should ask Chinese suppliers for documents that help them understand the product, supplier capability, order conditions, packaging, testing scope, and compliance assumptions. The right document list depends on the product category, target market, use case, and risk level.
Documents are useful signals, but they are not automatic proof. A certificate or test report should be checked for product scope, issuing body, date, model coverage, and whether it applies to the exact item the buyer wants to source.
Start with product documents
Product documents should help the buyer understand what is being quoted or sampled. Useful files may include product specifications, material details, dimensions, packaging information, user instructions, product photos, application examples, and available customization options.
If the supplier only sends a catalog, buyers should ask which products are actually produced by the supplier, which are trading items, which variants are commonly exported, and which details need confirmation before quotation.
Ask for testing and compliance information carefully
Depending on the product and market, buyers may need test reports, declarations, safety documents, material reports, chemical compliance information, certificates, or lab testing plans. The exact requirements vary by country, product category, and sales channel.
Buyers should avoid treating a document title as enough. They should check whether the report covers the same product, same material, same model, same standard, and same target market requirement.
Request business and order-condition information
Supplier comparison also needs commercial documents or written information about MOQ, lead time, payment terms, sample terms, tooling cost, packaging options, incoterms, warranty assumptions, and after-sales responsibility.
Clear written assumptions reduce misunderstanding. If suppliers quote under different conditions, the price comparison can become misleading.
